N VE N IQ Q3 omeph fligginwzfi LIQUID--FUEL-SUPPLY SYSTEM OF To all whom it may concern:

Be it known that We, JOSEPH HIGGINSON and Hum: '1 ARUX EL, subjects 01 the King of Great Britain and Ireland, and residents of Sovereign Works, Stockpors, in the cennty of Chester, Englencl. have in vented certain new and useful improve ments Relating to iquid-Fuelfiupply S'ye fame of Internnl-Combus'bi0n. Engines, which ihe follewing is a. speeific-etion.

This invention relates to liquid fuel snpplysysteins of internal combustion en gines of the type in Whicli the fuel is dz? .Wn from a lOW level tank or vessel. to an intern'ieiilinte vessel QEIOH'LWl'llCi} it is niselia 'gecl by gravity to the engine ca-i'bmetei'.

9m invention comprises *improvl arrangement of the means for contrclling the suction or vacuum cenneclvion and also, if desired, of the etmoe'plieiie connee ien of the inierniediaievessel.

Referring to the accompanying" erplnnatel-y clm'-.vings:-

3. In liquid fuel supply apparatus for internal combustion engines, in combination, a vessel into which fuel is drawn by suction and from which it is discharged by gravity, a float operated valve in said vessel acting to control the fuel inlet to said vessel, a vacuum pump, an atmospheric connection, and positively timed means controlling comnumication between said pump, said atmospheric connection and said vessel, as set forth.

4. In liquid fuel supply apparatus for internal combustion engines, in combination,

a vessel into which fuel is drawn by suction -25 and discharged by gravity, a float operated 'alve in said vessel acting to control the fuel inlet to said vessel, a vacuum pump, an atmospheric connection, and a continuously rotating plug cock controlling communication between said pump, said atmospheric connection and said vessel, as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
